In Russian, both the noun student 'student' and the noun $d u b$ 'oak' are masculine, but there are slightly different declensions for animate and inanimate nouns. Discuss the paradigms below in terms of the patterns of syncretism they display (data from Corbett 1991: 166):
$\begin{array}{lll}\text { Singular } & \text { student 'student' dub } \\ \text { Nominative } & \text { student } & \text { dub } \\ \text { Accusative } & \text { studenta } & \text { dub } \\ \text { Geritive } & \text { studenta } & \text { duba } \\ \text { Dative } & \text { studentu } & \text { dubu } \\ \text { Instrumental } & \text { studentom } & \text { dubom } \\ \text { Locative } & \text { studente } & \text { dube } \\ \text { Alwal } & & \\ \text { Nominatine } & \text { studenty } & \text { duby } \\ \text { Accusative } & \text { studertov } & \text { duby } \\ \text { Geritive } & \text { studentov } & \text { dubov } \\ \text { Dative } & \text { studentam } & \text { dubam } \\ \text { Instrumental } & \text { studentami } & \text { dubami } \\ \text { Locative } & \text { studentax } & \text { dubax }\end{array}$
